6 that cough and respiratory irritation can result from topical application of capsaicin Although it was first reported that human Hakas, 1990, Rumsfield and West, 1991 ; . bronchial tissue was affected by tachyphylaxis a rapid immunization against the effect of toxic doses of an extract ; under experimental in vitro conditions Lundberg et al., 1983 ; , an acute inhalation of capsaicin in human subjects challenged with repeated doses was observed to not induce tachyphylaxis Choudry et al., 1989 ; . Blanc et al., 1991 ; measured three respiratory indices; prevalence of respiratory symptoms, alteration of lung function and an increase in the cough threshold, in order to determine the effect of capsaicin in workers who had been chronically exposed to hot chili peppers. The induction of cough in exposed workers through the inhalation of capsaicin ranged from 3 x 10m7 to 3 x 10" M i.e. pg ul ; . The diluent was 1% ethanol in normal saline. ] In comparison, strong bronchial contractions were measured in cultured bronchial tissue in vitro ; with 10S5 M of capsaicin Lundberg et al., 1983 ; . The bronchoconstrictor effect of capsaicin both in vivo and in vitro is mediated through substrate P. Although it is known that capsaicin can elicit cough in man, Blanc et al., 1991 ; concluded that it did not alter lung function nor did it appear to increase asthma or wheezing except in one subject. The exception was a non-asthmatic subject whose FEV, forced expiratory volume ; dropped by 24% while the asthmatic in the study did not respond any differently than the other subjects. The authors were unaware of any reported cases of occupationally induced asthma due to Capsicum. It would appear that attempts to regulate coughing through respiratory flow rates may not be successful because Barros et al., 1991 ; reported that "lower inspiratory flow rates were associated with a greater cough stimulus in the capsaicin challenge". When it appears that the respiratory sensitivity of certain individuals has been aggravated because of cough induction by capsaicinoids, the noted coughing is more than likely to reflect an abnormality in the pathophysiology of the cough reflex, itself Fuller, 1991 ; . Fuller also reported that opiates inhibit capsaicin cough. Inhalation of capsaicin 4 - 65 pmol l; which may be expressed as 610 mg l - 19.8 g l ; induced coughing in all 17 subjects with the number of coughs being dose The mild asthmatics of the study demonstrated no evidence of dependent. hypersensitivity. Furthermore, there was no evidence - it must be emphasized, under their experimental regimen mild asthmatics, low doses ; - of bronchoconstriction Collier and Fuller, 1984 ; . The effect of higher doses or low doses with more severe asthmatics has not been determined but it is possible that these situations could produce severe bronchoconstriction Fuller, 1992, personal communication.

Metoprolol is a 1-selective adrenergic blocking agent, commercially available as oral tablets and an injection. It is commercially available as a racemic mixture and occurs as a white, crystalline powder with a bitter taste and is very soluble in water and freely soluble in alcohol. It has a pKa of 9.68. Metoprolol exhibits less than 3% loss in potency under the conditions used in this study. Several reports support the stability of metoprolol in various vehicles and at various pH levels, including one study at pH 4, 7 and 9 and bumetanide.

Uses acute bronchial asthma and reversible bronchospasm associated with chronic bronchitis and emphysema. Chronic Obstructive Pulmonary Disease COPD ; character izes itself with low retractable obstruction of the bronchial tree. It is considered that the inflammatory process, which leads to the obstruction, is resistant to the usage of corticosteroids. However the medications found its place in this disease treatment. This paperwork describes the influence of the usage of corticosteroids in treating the clinical symptoms of COPD, the influence of such medications on the decrease value of FEV1, on the frequency of exacerbations as well as the time of survival of the ill people. The side effects of the corticosteroids were also discussed in the paperwork. Current guidelines of COPD treatment in the field of the usage of such medications were analyzed and buprenorphine.
